Technologies / User Interface Add-Ins / Geographic Information System (GIS) Views / Map with Thematic Markers
In this example we use ColorBrewer to generate marker colors.
To use ColorBrewer, include it in the view:
<js file="colorbrewer.js"/>
Call
colorbrewer2rgb()
to set the marker symbol colors passing the name of the desired color brewer scale with the number of colors needed:
markerProperty.symbolColors = this.mapControl.colorbrewer2rgb(colorbrewer.Paired2[12]);
The Colorbrewer scales are pictured here:
